Firefly + 360 Servo Motor

Hello, I am trying to control the direction/degree of a servo motor but when I input the value it keeps rotating in the clockwise direction only. I am using a Tower Pro MG995 Servo 360-degree motor. Is there a way so that I can rotate it clockwise as well as anti-clockwise as per my desire. Like for 2 sec it should turn clockwise and then again to its original position. (7.0 KB)

Is there no expert with the knowledge of Firefly and Arduino Board on this forum! Also, I wanted to ask is there a way to control the servo motor on a timer! To give an instance I just want to run my servo motor for 2 seconds and then stop it.
